Overnight Steel Cut Oats Oatmeal made in a slow cooker with banana, cinnamon, vanilla, and naturally sweetened with pure maple syrup is a warm and cozy way to start the day! 100% whole food plant based recipe.


  • 1 1/2 cups steel-cut oats
  • 3 cups water
  • 3 cups unsweetened almond milk (or your favorite plant milk)
  • 12 ripe bananas (about 3/41 cup), mashed
  • 1/4 cup pure maple syrup
  • 1 1/2 teaspoons cinnamon
  • 1 teaspoon vanilla extract or vanilla powder
  • pinch of mineral salt

Optional toppings

  • chopped walnuts, almonds or pecans
  • banana slices or fresh berries
  • goji berries or toasted coconut


Grease bowl: Lightly grease the sides of the insert with oil. This will keep the mixture from sticking to the sides, but can be optional.

Slow cooker: In a 4 – 6 quart crock pot, place oats, water, milk, mashed banana, maple syrup, cinnamon, vanilla and pinch of salt, stir to mix, cover and cook on low for 3 – 5 hours, or up to 8 hours for overnight. If you can, it does help to stir 2 -3 times during cooking, but is not necessary.

Cool down: Once done, give a good stir, and let cool a bit. Oats will thicken upon standing. Add a tad extra non-dairy milk or water as needed to create desired consistency. Adding more liquid will create a creamier consistency.

Serve: Spoon into individual serving bowls and top with any of the optional toppings of choice. Drizzle a little non-dairy milk over top if you like.

Serves 4 – 6

Store: Leftovers can be stored in an airtight container in the refrigerator for 5 – days. Can be reheated with a little milk or water on the stove top over low, or in the microwave for a minute or two.


Make this virtually fat-free by omitting nuts.

Bananas can be mashed smooth or left a little chunky. Also, try subbing the banana with pumpkin puree.

I do not recommend substituting old-fashioned or quick cooking oats in place of the steel-cut oats as regular oats require less liquids.
